Logical unit size expansion on HDS Lightning
The Storwize® V3500 system supports Logical Unit Size Expansion (LUSE) with certain restrictions.
The following restrictions apply:
- Before LUSE can be completed on an LU, the LU must be unmounted from a host and have no available paths. The LUSE function destroys all data that exists on the LU, except for LUs on a Windows operating system.
- LUSE must not be completed on any disk that is managed by the Storwize V3500 system.
- If data exists on a disk and you want to use image mode to import the data, do not use LUSE on the disk before you import the data.
